Coolant Leak From Radiator on BMW X5

Problem Description and Possible Solution

It is not uncommon for the radiator to develop a coolant leak. A leaking radiator will require replacement. When a leaking radiator is replaced the entire cooling system should be inspected and if any additional leaks are found they should be repaired also.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

Similar issue. Sensor went off for low coolant, but did not notice anything leaking from the radiator. had the coolant topped off as it was extremely low. It was not until I had the engine overheat that the towing company noticed the radiator fluid leaking from my car. Had to have it and the thermostat replaced.

Radiator leak caused "water coolant temperature" alarm. Pulled over, got car towed to dealer. Radiator was replaced and 4 weeks later a new "water coolant temperature" alarm. Waiting on call back from dealer on what to do now!
